Subject: Allow dehardcoding documentation branch and URL in docs links

This makes it possible to change the branch of the documentation that
URLs are pointing to without having to modify all class reference
files.

In the XML class reference, the `$DOCS_URL` placeholder should be used,
and will be replaced automatically in the editor and when generating
the RST class reference.

The documentation branch string is set in `version.py`.
